Corps proposes voluntary buyouts outside levees

Storm surge from Hurricane Katrina pushed through marsh along the north shore of Lake Pontchartrain at its juncture with the Tchefuncte River, reaching a record high 7.9 feet in Madisonville, where it damaged 40 percent of the historic waterfront town's homes.

But it still came as a surprise to Madisonville Mayor Peter Gitz to learn that the Army Corps of Engineers may recommend a voluntary buyout of properties south of Louisiana 22, which bisects the town, as part of the corps' comprehensive plan to protect south Louisiana from catastrophic hurricanes.

Gitz and others are learning what flood protection from a "Category 5" hurricane, the classification for the most intense storms, could mean for the New Orleans area. While the corps is still working on its Category 5 plan, a "progress report" obtained by The Times-Picayune offers a preliminary look at the agency's three-pronged approach to protecting the region: flood control, coastal restoration and "buyout" zones.

Yes, buyouts.

Part of Madisonville -- along with hundreds of acres in other wetland or low-lying areas outside of proposed levee systems -- appears so vulnerable to storm surge that a government buyout of residences and businesses is listed as one potential option.

The areas pictured also include the southernmost parts of Slidell, Mandeville and Lacombe on the north shore; Delacroix and Reggio in St. Bernard Parish; Ruddock in St. John the Baptist Parish; Lafitte and Barataria in Jefferson Parish; and a number of communities on both sides of the river in Plaquemines Parish. The report doesn't say how many buildings are in the areas proposed for buyouts.
